Perimenopause, or menopause transition, begins several years before menopause. It's the time when the ovaries gradually begin to make less estrogen. It usually starts in a woman's 40s, but can start in her 30s or even earlier.

How Long Does Perimenopause Last?

The average length of perimenopause is 4 years, but for some women this stage may last only a few months or continue for 10 years. Perimenopause ends when a woman has gone 12 months without having her period.

Are My Perimenopausal Symptoms Normal or Something to Be Concerned About?

Can I Get Pregnant If I Am Perimenopausal?

Yes. Despite a decline in fertility during the perimenopause stage, you can still become pregnant. If you do not want to become pregnant, you should use some form of birth control until you reach menopause (you have gone 12 months without having your period).

For some women, getting pregnant can be difficult once they are in their late 30s to early 40s due to a drop in fertility. If becoming pregnant is the goal, there are treatments that can help you get pregnant.

Talk to your doctor if you are having problems with your sex drive. He or she may be able to recommend a counselor or therapist to help you and your partner work through this problem. Vaginal lubricants may also be recommended, if vaginal dryness is a problem.

Other treatments available to help with the various symptoms of perimenopause may include antidepressantmedications for mood swings.

Talk to your doctor about your specific symptoms and goals of treatment. This will help him or her make a plan that is right for you.
